How to prank people at school

This is a good prank to pull on people at school. The computers at school are all connected on the school network. If you do this right it will send messages to people continually.

IT DO NOT SAY "HAHA"!!!????????????????
I did this, but replaced the computer name with an *, and it went to every computer in the school district, about 6000 computers total. After crashing the network for a day, my friend asks me how to do it, so I show him. He gets caught, blaming me of course... After serving my 5 days of in school suspension, I have been banned from the computers until I graduate... So do NOT get caught, doing the same thing I did, I am just saying what you could do. (also, do not copy this to startup on several computers... ;-) )
I call bull-$hit on you. b/c it will only go to computers on a local network, thus only the comps connected to hub / router that you are connected to. and you can't connect a whole district to one router or hub.
Actually, this can happen because of how my school district is set up. We all log onto a server downtown. So from that server, it can go to all the computers. My friends dad, and another friend I know, setup the computers for the school district and this is what they told me. Just because you don't think it'll work doesn't mean that it won't.
It does happen because at my school, we are all on a ring for the internet, my school and the schools around my area so if one school or the master ISP goes down, all the schools are down for the day
you may log onto a server, but your computer is connected a router or hub. Net send will only send the message to other computers on that local network (the comps connected to the hub or router). If you could send messages outside of a hub or router then you could net send any computer in the world. I know it wont work because 1. I've tired it, 2. If it could work then you would have a pop up on your screen every couple of seconds form spammers 3. I have 3 years post secondary education with my minor being computer sciences. And its not I think it wont work, I know it wont work. If you want to net send me go ahead my ip address is 192.168.0.101, oh wait thats behind a router and is a common IP address for almost every router the world to assign. Net send only uses ip adress to send messages. thats why you can't send past a router. It could send out past a router if you were able to input in IP/CompName, Subnet Mask, Default Gateway, Mac Address, And the IP of the router (one given out by your ISP. So, once again I call Bull $HIT!

What about network trees and VPN's..? That's how the elementary schools here are configured
no this will work
I too showed somebody the "star" method. Within seconds 3 teachers were converging on his position because all the messages include the computername of the sender. I'm sure he hadn't thought far ahead enough to realise that his message was going to EVERY computer in the college, including the admin's computer, and the priciple's. I'm also pretty sure that he regrets sending a message that insults the readers mother. I never saw that person again.
All I can say is OUCH.
How true...
AWESOME!!! I need to do this!!! does it tell the tech people what computer its coming from?
They can trace it so as soon as you send it, GTFO and keep a low profile about it. Or if you want to do other things, just pull out the internet plug. They'll just think it is a malfunction, but they can still trace it... How can they trace it? When the message appears on everyone's screen, the title of the message (the bar at the top) wil say Message from (computer address) @(time sent) and all the tech guys have to do is read that and come running to the computer from which the message originated...
... how do you remove this? could you do like a clear thing (similar to command prompt) in the code?
According to my brain, there is no known way to do that. If you were desperate, you could install a messaging program like realtalk, but on a couple hundred computers, that would take a very very long time...
Basically, just throw your comp in the river and let it drift into the ocean, and they'll never be able to find the culprit. Make sure u do this at ur house 1hr before you move to a new home. Oh ya, dont forget that satellites may track that message to the old home
I don't think that the council would appreciate a computer floating past their window... And wouldn't the IT coordinator be just a tiny little bit cross with you lobbing school computers out the window?
OMG dats rad.
oh snap. dude i did this too. shut down the whole network for 2-3 days. Modified the code, so that it called itself, running itself exponentially. Basically had almost one billion iterations of my messages on every computer in the district. My punishment was to fix it. and then never touch a computer again.
HAHAHAHA that is really funny for some reason. what grade were you in?
Or, if you can, log on in an administrator access username.
Lol, you should have just said you don't know what he's talking about. I value my life over my friends :P

any administrator worth their salt would have messaging service turned off on their network....so in most places this won't work
Most school network admins are just overglorified typing or physics teachers.
Some just say, "screw it with security, DOS is a foreign language to students"
I'm a student and DOS ain't a foreign language to me! However, our admin learned from experience... two years ago, kids were shutdown -s -f -t 10 -m \\computer and shutdown -i ing all over the place. So it's blocked. So is any use of msg, although I haven't yet figured it out on my home machines. And we use 7 now so net send is out of the question. There goes any hope of sending messages with CMD...
i personally would disagree that that's the norm....it does happen often though
lol... I did this in school last year! but since it was April 1st when i did it, the principal let me get away with it... But apparently the tech dudes that come to our school every once and a while to set stuff up and fix stuff, didn't know how i did it... I'm guessing they found out though because they didn't ask me...
i remember my teacher didn't the least bit mad when i dumped a full pencil sharpener down my "friends" back

 So how do you make it so it only sends the message once?
 Or a certain number of times. for that matter.

I can't do this at my school.  Damn school is too smart, when we click start, all that comes up is a tiny box that says shut down and log off.  I can't acess any of the computer's functions.  I even tried using my flash drive to open Windows Explorer, still all funtions blocked.  Damn!!  =(

Doesn't work; command prompt comes up and repeats a message.

how do you know the computer number

i typed in * for the computer name and it keep saying MESSAGE SUCCESSFULLY SENT TO DOMAIN SBHS

but nothing happens on other peoples computers

please help
  • is a wild card. Instead of sending it to just one computer, it sends to every computer on the entire network! Unfortunately, this includes all the admins...
It's probably not working because one of the admins on your network system (SBHS) has a firewall blocking it.
Oh god. It did that weird list thing. Let me try again:

t*he* ch*a**ra*cter I*m **t*al*ki**ng a*bou**********t a**ppears **a w*hol*e *l*o*t* *i*n* ***thi**s *se**n*t**en*ce**
